(A) Cross-linking of 18S-e(α) RNA probe to ribosome subunits. (B) Competition of cross-linking of S15 RNA probe with various unlabeled RNAs. The first lane (No comp.) is in the absence of competitors, the second lane is in the presence of polyC as a nonspecific competitor, and the third lane is in the presence of 18S-e(α), an RNA complementary to the same region of the 18S rRNA as the S15 mRNA. Competitors were used at a 10-fold molar excess over probe. The positions of the rRNAs were determined by ethidium bromide staining of the agarose gels.
